Tone remote controller (Kensal Green)

Re-offered before trashing as there were no takers last time. I have to give away a PANASONIC EASA-PHONE Tone Remote Controller, Model no. KX-A74. I bought it a long time ago in the days before mobile phones to access my answering machine and retrieve my messages at home when I was away. It is still in excellent working order with a working battery. I realise no one is likely to need such a device now and I may well have to throw it away.
